Barium strontium aluminosilicate glasses with additions of lanthanum oxide and/or zinc
oxide are potential sealing glasses for planar solid oxide fuel cells (pSOFCs).
The thermophysical and structural properties of different series of these glasses
are being studied to understand their property composition relationships.
Thermal analysis and dilatometry are being used to assess the thermal properties of the
glasses, while the glass structure is being studied by Raman and Fourier transform
High temperature mechanical test measurements and electrical
measurements are also being undertaken. This talk focuses on how these properties
vary with the compositions of these glasses.
